Principle of operation
When the automatic cleaning filter is started from a static state, water flow enters the machine body 10 from the water inlet pipe 35, the water flow is firstly filtered from the inner filter screen 18 and flows to the outer side from the inner side of the inner filter screen 18, purified water is discharged from the water outlet 49 at the bottom, when dirt on the inner side of the inner filter screen 18 is increased to block the filter screen on the surface of the inner filter screen 18 to a certain extent, the internal pressure of the machine body 10 is increased, the hydraulic pressure enables the diversion piston head 13 to move upwards, the inner filter sealing block 28 moves upwards and contacts with the machine body 10, the diversion piston head 13 continues to ascend, the sewage discharge sleeve 16 and the sewage discharge inner cylinder 20 slide relatively, the sewage discharge hole 58 of the inner cylinder is aligned with the sewage discharge hole 57 of the sleeve, and the sealing block 15 contacts with the machine body 10 to close the inner filter.
At this time, the lane changing piston head 13 makes the sliding through head 11 move downwards through the lane changing hydraulic cavity 39, meanwhile, the bottom of the lane changing piston head 13 is clamped at the lane changing gear lever 42 for fixing, water flows to the outer filter screen 17 through the outer water channel 12 for filtering, most of the purified water filtered by the outer filter screen 17 flows to the water outlet 49 through the outer water purifying valve body 59, a small part of the purified water flows to the inner filter screen 18 through the inner and outer filtering through holes 54 for back flushing the inner filter screen 18, and dirt on the surface of the inner filter screen 18 enters the inner sewage discharging barrel 20 through the position where the inner barrel sewage discharging hole 58 is aligned with the sleeve sewage discharging hole 57 after being flushed, and is discharged out of the machine body 10 through the inner sewage discharging hose 25.
When dirt on the surface of the outer filter screen 17 is accumulated to increase the pressure at the outer water channel 12, the blocking rod piston 45 moves upwards to enable the channel changing blocking rod 42 to retract inwards, meanwhile, the sliding through head 11 applies pressure to the channel changing hydraulic cavity 39 to enable the channel changing piston head 13 to move downwards to close the outer water channel 12, most of water flows to the water outlet 49 after passing through the inner filter screen 18, a small part of water flows to the outer filter screen 17 through the inner and outer filter through holes 54 to be aligned for backwashing, and the washed sewage flows to the outer sewage outlet 21 and is discharged out of the machine body 10.
When the internal and external filtration is alternated, the water pressure in the water inlet pipe 35 generates large fluctuation to generate the water hammer phenomenon, the water pressure peak value pushes the water hammer preventing piston 36 to move upwards, the pressure in the water inlet pipe 35 is relieved, and the water inlet pipe 35 and the machine body 10 are effectively protected.
When outer filter screen 17 or interior filter screen 18 through long-time erode, when the surface clearance increases even breaks, rivers will reduce by a wide margin at the pressure that outer filter screen 17 or interior filter screen 18 department produced, only have one in outer filter screen 17 or interior filter screen 18 two to appear the decompression, then the condition of both decompression simultaneously can appear when inside and outside filtration alternative process, outer kelly 40 and interior kelly 41 will break away from with gate valve kelly 30 simultaneously this moment, gate valve piece 34 rebound and carry out the shutoff with inlet tube 35, prevent that unfiltered rivers from toward delivery port 49 department.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
